I already have a similar product installed in my westy, over the sink/stove. I got it from http://autolumination.com/homefixtures.htm
It is essentially the same thing, but with adjustable positioning of the lights on the track and wired directly into the van. You also
need to put in a switch somewhere to turn it on/off but it is really a simple install - if I can do it anyone can (yes, I am admitting I am
an idiot). The cost may be higher, however, especially if you get the LED bulbs they are selling. They do have regular bulbs available
that are inexpensive, but I went with the LEDs to reduce drain on my second battery. I will work on taking some pics and getting
them posted if enough people are interested. I really like the setup because it provides a lot more light than the standard dome light
in my '81. I also like the fact that it is wired into my van because I hate buying/changing batteries all the time.
